Objective To investigate the best postures of patients with cystolithiasis for extracorporeal shock wave lithotripsy(ESWL) treatment.

目探讨体外冲击碎石术(ESWL)治疗膀胱结石较佳体位。

According to the syntaxis skill of shock wave and the theory of effective charge,the annular conical booster pellet structure is designed.

根据冲击汇聚技术原及有效论,设计出环锥形传爆结构。

Experiments on influence of shock wave with some strength on components of blood were conducted in a diaphragmless shock tube developed in our laboratory.

用自研制无膜激管，研究在一定强度激用下，激对血液成分影响。

Most of the work was based on experiment results, and some empirical formulas of shock wave peak pressure, electroacoustical efficiency, and plasma parameters were obtained.

这些机获得绝大部分基于实验结果，如已经获得了一些冲击峰值压力经验公式，电声学效率，以及等离子体参数。
